What is Brock Lesnar’s UFC record? Find out which illness is said to have put an early end to his MMA career here

Brock Lesnar had one of the most unique careers in UFC history, building a 4-3 (1 NC) record. He was immediately thrown in with the top heavyweights in the division and excelled.

After a dominant debut against Min Soo Kim, 'The Beast Incarnate' got the attention of UFC president Dana White and convinced him to give him an opportunity to compete in the top promotion in the sport.

White did just that, but didn't give the former WWE champion an easy opponent by any means. He was booked in a fight against former heavyweight champion Frank Mir at UFC 81.

Despite the submission loss in his octagon debut, Brock Lesnar clearly made an impression on the UFC president and the fans as he was clearly winning the fight prior to getting caught with a heel hook. After earning his first UFC win over veteran heavyweight Heath Herring, 'The Beast Incarnate' then challenged Randy Couture for the heavyweight championship at UFC 91.

Lesnar dropped Couture with a right hand and finished him with ground strikes to become the new UFC heavyweight champion in only his fourth professional fight.

At UFC 100, the pro wrestler-turned-MMA fighter successfully retained his heavyweight championship and at the same time avenged his lone career loss to Mir, earning a second-round TKO win via vicious ground-and-pound.

Months later, Lesnar developed diverticulitis and required surgery, which kept him out of action for almost a full year. He returned at UFC 116, where he defeated interim heavyweight champion Shane Carwin in impressive fashion after narrowly avoiding a TKO loss in the first round. He ended up submitting Carwin via triangle-choke in the second.

Lesnar's title reign came to an end three months later at UFC 121, when Cain Velasquez finished him with strikes to earn a first-round TKO. He developed diverticulits again, which kept him out of action until UFC 141, where he fought Alistair Overeem. After a second-straight TKO loss, he announced his retirement from MMA.

Despite retiring, WWE allowed Brock Lesnar to compete in a one-off fight against Mark Hunt at UFC 200. He defeated Hunt via unanimous decision, but it was later overturned because Lesnar tested positive for a banned substance. The no contest resulted in his MMA record being 5-3 (1 NC).

What did Brock Lesnar accomplish prior to his UFC career?

Prior to his foray into MMA, Brock Lesnar was a former NCAA Division 1 National wrestling champion and WWE superstar.

After spending time in the developmental system, 'The Beast Incarnate' made his WWE debut on the Monday Night Raw after WrestleMania X-8, quickly becoming one of the organization's biggest stars.

He won the WWE championship, headlined WrestleMania, and became the cover athlete for the video game; WWE SmackDown: Here Comes the Pain!

'The Beast Incarnate' became unhappy in WWE, though, and decided to try something different. After leaving WWE in 2004, he attempted a transition to the NFL, but was one of the Minnesota Vikings' final roster cuts.

It all worked out for him as he later committed himself to MMA and became a UFC heavyweight champion.
